Answer: D. Dollar Diplomacy.
Step-by-step explanation:
Dollar diplomacy was the foreign policy of the United States intended to strengthen control over Latin America and East Asia through economic power by providing loans to foreign countries. The idea behind this policy was that the United States had an obligation to intervene in unstable countries vulnerable to European control.
President Theodore Roosevelt first applied this strategy in 1904 with his Roosevelt Corollary to the Monroe Doctrine. Taft maintained and developed that same policy.
